根据体模和两名患者的螺旋计算机断层扫描 (CT) 血管造影数据，对连续正交动脉横截面、节段长度和曲率进行半自动量化。平均直径和曲率的测量值与参考值相关 (r(2) = .99)，平均直径和曲率测量值的平均分数误差分别为 0.07 和 0.06。体积测量显示出提高 CT 血管造影的准确性、精密度和诊断实用性的潜力。
Contiguous orthonormal arterial cross sections, segment lengths, and curvature were semiautomatically quantified from helical computed tomographic (CT) angiographic data in phantoms and two patients. Measurements of mean diameter and curvature correlated with reference values (r(2) = .99), and mean fractional errors were 0.07 and 0.06 for mean diameter and curvature measurements, respectively. Volumetric measurement showed a potential to increase the accuracy, precision, and diagnostic utility of CT angiography.
